TB20 Digital-output-module, DC 24 V, 700mA, HF 8x
The scope of delivery already includes the appropriate front connector for the cabling and a base module. The TB20 module has 8 high-feature digital outputs with an output power of up to 700mA.
The status display of the outputs is signalized on the module via green and red LEDs.
There is also monitoring and diagnostics of the 24 V load voltage, excess temperature and short-circuit monitoring to ground for each channel.
Channel status information can be read into the PLC via the input image.
Channel LED signals
| Off | Output off |
| Solid green light | Output on |
| Solid red light | 24 V load voltage (L+) missing |
| Flashing red light | Short circuit to GND detected |
